Description
The MASWSS0143 is a GaAs monolithic switch in a
lead-free, SOT-26 surface mount plastic package.
This device is ideally suited for applications
where very low power consumption, low
intermodulation products and very small size are
required.
Typical applications include internal / external
antenna select switch for portable telephones and
data radios. In addition because of its low loss, good
isolation, and inherent speed, the MASWSS0143
can be used as a conventional T/R switch or as an
antenna diversity switch.

The MASWSS0143 can be used in power
applications up to 3 watts in systems such as cellular
PCS, CDMA, W-CDMA, TDMA, GSM and other
analog / digital wireless communications systems.
The MASWSS0143 is fabricated using a 0.5 micron
gate length GaAs pHEMT process. The process
features full chip passivation for increased
performance and reliability.

Handling Procedures
Please observe the following precautions to avoid
damage:
Static Sensitivity
Gallium Arsenide Integrated Circuits are sensitive
to electrostatic discharge (ESD) and can be
damaged by static electricity. Proper ESD control
techniques should be used when handling these
devices.
† Reference Application Note M538 for lead-free solder reflow
recommendations.
Plating is 100% matte tin over copper.
